2 Claims.

My invention relates to improvements in applicator rolls.

Roller devices for applying color coats to wall surfaces either in overall or patterned designs have heretofore been provided for use with water color to similar paints and wall coatings. Such applicators and applicator rolls have usually been formed of rubber, sponge rubber, or material containing a rubber base which has been adapted for use only with water color or with wall coatings from which oils such as linseed oil are absent. The presence of oils causes rubber or rubberized materials to swell and become distorted. Likewise they are subject to extreme slippage as the applicator is moved over a surface to be coated.

The object, therefore, of my invention is to provide an applicator roll usable with oil paints and wall coverings containing oil and which may be made in shapes and patterns for applying designs of different degrees of complexity without slippage of the roll andwithout danger that the design, however conventional, may be repeated irregularly over large wall surfaces by an amateur operator.

Another object of my invention is to provide a special frame for holding my new applicator and to provide special types of paint supply containers to feed paint or other wall coatings to my new applicator roll. Another object of my invention is to provide a single roll which may comprise a paint container and paint applicator wherein danger of leakage of the supply of paint in excessive amounts to the actual applicator pads upon the applicator roll may be avoided.

In the drawing:

Figure l is a plan view of my applicator roll and feeder roll, and a frame for holding both rolls.

Figure 2 is a side elevation of the structure shown in Figure 1.

Figure 3 is a section on line 3-3 of Figure 1.

Like parts are identified by the same reference characters throughout the several views.

As shown in Fig. 1, my complete device includes an applicator roll ID, a paint feeder and container II, and a frame l2 provided with a handle 13 for supporting the rolls in their proper relation to one another and for supporting the applicator roll In in a position for application of paint to a wall surface.

The applicator roll l0 comprises a center core l4 preferably of resilient material which may comprise sponge rubber if it is properly shielded from the paint, or it may comprise any other resilient material disposed upon an axis l5 of suitable solid material for maintaining the general shape of the roll and for reception of a trunnion I 6 at either end thereof.

The trunnions are received in the frame It! as indicated most clearly at H in Fig. 1. Upon the exterior of the core M I provide a compositionv surface material l8 which is unaifected by the oils of which paints are usually made but which is sufficiently resilient to yieldingly engage the surface of a wall to be painted with a pattern. I am not aware that any material suitable for this purpose has been provided in a form of a. composition which will prevent slippage of the roll in its rolling passage over the wall surface. I therefore form the pattern upon the surface of the material ill with a special surface material which will not slip.

The material which I provide as a surfacing material-for the portions of the roll l0 intended to contact the wall surface, comprises comminuted felt or wool felt fibers impregnated into the surface so that a considerable amount of wear of the fibers may develop in the use of my applicator roll without interfering with the eflicacy of the working article.

I usually cast the material of which my applicator roll is made in a form provided for the-purpose, and I carve or machine the form so as to provide depressions into which the material may be cast to form the high points of the pattern comprising the wall contacting parts of my ap plicator. In to these depressions I sift a suitable quantity of wool felt fibers so that when the hot molten material I 8 of the roll is cast into the mold the wool felt fibers are incorporated in the ultimate surface and are held tightly by the cooled mass.

The pattern in which the surface of my applicator roll is cast may be decidedly accurate as to its configuration, since the material does not contain rubber and the oils of the paint will not distort the pattern by causing it to swell. Any conventional pattern or any overall pattern such as that used for applying a tiffany surface to the wall may be selected.

Assuming that a wall surface has been covered with a solid color by the usual methods with brushes or spray guns, and assuming that my applicator roll Ill is being used to apply a pattern in another color upon said surface, I provide in the frame I2 provision for mounting an additional roll II which comprises a foraminous container 20 into which liquid paint may be poured through apertures 2| in the end of the container. Around the cylindrical surface of the container III provide a sleeve or casing 22 which is composed of a material not impervious to paint, so

that the paint within the foraminous container 20 may pass through the casing 22 and be applied in the rotation of the roll II to the high points of the roll 10.

Casings heretofore provided for a foraminous container 20 have usually been made of felt and are subject to shrinkage so great in extent that in rolls ll heretofore provided the casing 22 has shrunk sufliciently during operation to uncover the holes of the foraminous container. I therefore provide a casing 22 sufliciently long to fold over the ends of the foraminous container 20 where'it will be seen that the margins 23 of the casing 22 may be clamped to the end of the container 20 by means of a clamp plate 24 secured to the container by means of a thumb nut 25. No amount of shrinkage of the casing will then cause the margins 23 to be withdrawn so as to permit of the leakage above referred to.

In the handled frame in which I mount the rolls I 0 and ,trunnions l6 are receivable at I! in the extremity of the frame. Trunnions 26 at the ends of roll- II are receivable in any one of several sockets 21 in the frame [2, and a special frame guard 28 pivoted upon the extremities of the frame I2 is adapted to move to a position indicated in Fig. 1 through an arc as indicated in Fig. 2, and is secured in the position indicated in Fig. 1. by a spring clip 29 adjacent the handle IS. A plate 30 on the guard 28 holds the trunnions I6 and 26 in their proper places during the operation of my devices If the roll l0 requires a large diameter in which to delineate a particular type of conventional pattern, the roll II will be positioned in a notch 21 farthest from the trunnions I6. Resiliency of the surface material of the roll l0 takes care of any moderate discrepancy in the location of the roll H.

In the use of the applicator roll ID with the felt surface upon the high points delineating the pattern, I have found that an amateur may, in a few minutes, apply a painted conventional design to an entire wall surface or to major portions thereof without previous experience and without danger of slippage of the roll upon the surface so as to interfere with the registry of the critical points of the pattern at the proper places in the wall surface. Any other material of which I am aware will not perform the function specifled above.

I claim:

1. The combination with an applicator roll of resilient material, of a surface therefor comprising felt fibers impregnated into said material.

2. The combination with a resilient applicator roll providing a patterned surface delineated by high portions of the roll, of a surface for said high portions comprising comminuted felt matted and impregnated into the resilient material of the roll.
